Schisin Ndongson, a PhD student at pervasive Systems Group, presented his paper Titled “Comparative Analysis of Topology Changes in FSO and RF Spatial Networks Under Node Mobility and Weather Variability” in IEEE WCNC 2025, held in Milan, Italy.
The paper presents a comparative analysis of the dynamicity in RFSNs and FSO-SNs, providing valuable insight into the rate of topology change. The analysis reveals that, on average, topology changes occur every 43.6 seconds in FSO-SNs, with a total of 1981 topology changes during a period of 24 hours, 61.4% of which occur within 41 seconds after the previous change. In contrast, RF-SNs experience only 441 topology changes, with only 20.6% of these occurring before 41 seconds after the previous change. Furthermore, they analysed the impact of weather conditions on the maximum achievable data rates for both FSO-SN and RFSN technologies, observing drastic fluctuations in Free Space Optical (FSO) systems. This study provides a solid foundation for developing tailored routing solutions for FSO-SNs.
